I am also planning a bridal shower! Actually, I am planning both the bridal shower and the bachelorette party, so I am in the same boat. You have probably already though t of some of these ideas, but just thought I'd give you some suggestions:

- lewd/sexy ice cubes OR sexy drink straws! you can buy the molds at lingere/sex toy stores, or even some places like party city or party america

- decorate the bride! Make her wear some of the decorations, like feather boas, princess crowns, naughty tshits, buttons, banners, etc.

- twinkle lights! You could do red or pink lights if that is the colors you are using.
